Symptomatic carotid stenosis (sCS), a common cause of transient ischemic attack (TIA), is correlated with higher stroke risk. We investigated the frequency and associated factors of sCS in patients with TIA and the association between sCS and stroke risk following TIA. ⋯ SCS appears to be associated with a higher risk of stroke in patients with TIA defined according to the tissue-based definition.
